What is mChapters

mChapters is a simple, intuitively and easy-to-use chapter marker editor for MP4/MOV files. Chapter markers will make it easy for users to skip a playing-time to a specific time. It's very useful especially in long duration videos and audios.

mChapters will save chapter markers data, times and titles, as text track into files. The text track is defined by the QuickTime/MP4 specification. So you can use it in media players supported that of QuickTime/MP4. e.g. QuickTime Player, iTunes, iPhone, iPad, iPod, Apple TV and so on.

mChapters will save files without re-encoding video/audio data. That does not affect the qualities, and that makes completing the saving quick.
